Configuration Options

Configuration options refer to certain options within the MCU that are programmed into the OTP

Program Memory device during the programming process. During the development process, these

options are selected using the HT-IDE software development tools. As these options are programmed

into the device using the hardware programming tools, once they are selected they cannot be changed

later by the application software. All options must be defined for proper system function, the details of

which are shown in the table.

No.

Options

Watchdog Timer: enable or disable

Watchdog Timer clock source: LXT, LIRC or fSYS/4

Note: LXT oscillator must be selected by OSC configuration option if WDT clock source is from LXT.
